Patented Mar. 18, 1930 UNITED s'm'rss FATE FRED G. HOOKE AND JAMES J.FLYNN, F LOWELL, EIIASSAGI-IUSETTS, ASSIGNORS OF ONE-FOURTH TO GARDNERW. PEARSON, OF LOWELL, MASSACHUSETTS V SHOE Application filed June 16,

This invention relates to shoes. Its purpose is to provide a shoe ofwhich the sole will be flexible and which will have the generalappearance of a Goodyear welt shoe but which is made substantially bythe process and machinery of a McKay shoe.

It has the further advantage that the shoe will not squeak.

We are aware that shoes are now made with an upper, an in-sole and amiddle sole or what is sometimes called a doubler or slip-sole fastenedtogether by through and through stitching, the edges of the middle soleextending out clear of the upper, and an out-sole fastened P 1 by sewingto the edge of this middle-sole.

Our invention consists broadly in cutting out a certain part of themiddle sole and preferably filling this with a plastic pliable filling.This middle sole is a flat piece of leather as distinguished from a weltwhich is a long strip bent around to the shape of part of the foot.

Its shape substantially conforms to the shape of that part of the outersole which is in front of the heel, and it is so cut out as to leave anopening or hole, the side edges of which are substantially equidistant,or parallel from its outer edges at all points down to the heel portion.It may or may not extend around the heel.

The principal feature is the hole cut out at the position occupied bythe ball of the foot. In the drawings, Fig. 1 is a cross section of acomplete shoe made according to our process viewed as on a line such as11 of Fig. 3,

except that the shoe is complete.

Fig. 2 is an elevation of a shoe of our construction with the toe partbent upward to show its flexibility.

Fig. 3 is a view from the bottom of a shoe in process of manufactureafter our middle sole has been sewed 0n and before the composition hasbeen applied.

Fig. 4 is a view similar to Fig. 3 showing a shoe with a slightlymodified type of our middle sole nailed instead of sewed in position,and with the cut out part filled with composition.

Fig. 5 is a bottom view of another modified type of our middle sole.

Fig. 6 is a bottom view of still another modified type of our middlesole.

Fig. 7 is a bottom view of still another modified type of our middlesole.

In the drawings U represents the upper, H the heel and O the outer soleof a shoe of ou construction.

I represents the inner sole and M-the middle sole of our constructionwhile L represents the lining of the upper and S the shank of wood ormetal. I I

In the preferred form of our middle sole, shown especially in Fig. 3, wecut out the 24 of the cut-out and the outer edge 21 of the forward partof the sole will be substantially parallel so that the part 21 can guidethe sewing machine guide which directs the needle for stitching 10 whichmay be of thechain stitch type or any other usual McKay type.

In such shoes, the stitching usually extends from a point such as 25just in front of the heel to a point 26 about where the curve of the toebegins, while around the toe portion the sole is nailed in position bynails such and poorgrade of leather for our middle sole M, we prefer tofasten around the toe by gluing or cementing acanvas or clothreinforcingstrip 30.

As shownin Fig. 4, we may use a middle sole N with a heel part 41 andcut out part 42 and 40, between which is a bridge piece or cross piece48. We find this cross piece keeps the sole from distortion and Welocate it preferably just across the end of shank S at'a point where itwill not be directly under the art 22 in such manner that the outer edger; Fries A I As we may Wish to use a relatively cheap preferably bysewing 11, near the outer edge thereof. I i

As shownin Fig. the heel '52 of our mid dle sole 50 which is cut outat51 may be sep- H r 1 arate from the. rest of the middle sole.

As shown in Fig. 6, we may use amiddle sole 60 in which the cut outpart" 61 is only 7 where bones at the ball ofthe foot will rest,

struction is a middle sole 70, cutout at 71 and 72 leaving a diagonalcross piece 7 3 which follows parallel tofiandbehind the bones at. theball of the foot where the foot and shoe 7 or in fact the cut out partmay be in any place and o f-any size to suit different types of shoes; IAs sl own*in- Fig. 7, we find a good connaturally bend,- I I 74 is acanvaszor; cloth reinforcementaround the-toe, where the nails go'.

squeaking is caused. This combinationof the The filler C is of a well'known plastic and 1 pliable type which is extensively used in Goodyearwelt shoes, and is softened by the,

heat 'ofthe foot, as a result of which it confonmsto the shape thereof.It remains plas ticand pliable, and fills, the cut out'space soaccurately, that there is no slipping whereby cutout middle sole and:the plastic pliable filling'thus allows a pliable shoe, which will Vnotsqueak; to be made on a McKay through and through stitching machine.
